Abstract

A color display tube comprising an envelope consisting of a neck, a cone, and a flat or slightly curved display window having a skirt which is substantially parallel to the axis of the envelope. The inner surface of the display window is joined to the inner surface of the skirt via a sharply curved surface. The display window has on its inside a substantially rectangular display screen comprising a material luminescing in at least one color and over which an aluminum film is provided. Means is provided in the neck to generate at least one electron beam. By making the outer periphery of the display window extend substantially parallel to the boundary of the luminescent material of the display window, and by making the camber a'/b' of the sides of the boundary outwards smaller than 0.01, (b' being the distance measured along a straight line between the corners of the boundary and a' being the maximum distance from the boundary to the line) a display tube is obtained having a uniform, apparently rectangular edge around the display screen.
